NI43-101 rules require that all disclosure be based on advice by a "Qualified Person" (QP). In some circumstances, the QP must be independent of the issuer and the property. To be designated a QP, it is not sufficient to simply be an experienced geologist or an engineer. The budding QP must be a member in good standing of a professional engineering or geoscience association which has an enforceable code of ethics (the Association of Professional Engineers of British Columbia, for example). New applicants to these associations are increasingly being forced to sit detailed ethics, law and professional liability examinations before they are admitted, ensuring they should (in theory) be familiar with their responsibilities as QPs.
